Although the removal efficiency of the activated carbon on SO2 and NO measured in this test is low, the activated carbon used in circulating fluidized bed flue gas desulfurization and denitration has the advantages of simple and reliable process, low system resistance, stable desulfurization and denitration, good economic and environmental protection, NO secondary pollution and so on.

The adsorption properties of activated carbon fiber or modified activated carbon should be further studied.

Activated carbon before and after modification was characterized by specific surface area measurement, scanning electron microscope observation, Fourier transform infrared spectroscopy measurement and Boehm functional group titration.

The results show that there are -OH, -C=O, -C-OH and other functional groups on the surface of activated carbon.

The surface functional group structure and specific surface area of the modified GAC were changed, and the changes of the surface functional group structure and specific surface area of the activated carbon prepared by different modification methods were different.

The specific surface area of activated carbon modified by nitric acid increased from 925.45m'lg to 960.52m2/g, and the number of acid functional groups (carboxyl group, phenolic hydroxyl group) increased from 0.23 mmol/g to 0.36 mmol/g, while the number of acid functional groups and specific surface area of activated carbon modified by reduction decreased.www.chinactivecarbon.com

In this paper, the basic principles of four oil and gas recovery technologies such as adsorption method, condensation method, absorption method and membrane separation method are described, and the oil and gas recovery technology based on adsorption method is systematically analyzed.

A kind of activated carbon material suitable for oil and gas recovery system by adsorption method was selected according to the design requirements.

The main equipment of oil and gas recovery system by activated carbon adsorption method, the activated carbon tank, is designed and calculated, and its strength is checked.

The flowchart of the oil and gas recovery system by activated carbon adsorption in the laboratory of Environmental Engineering Department is also drawn, and the system is simulated in three dimensional.
